JOHN JOHNSON, OF NEW YORK, N. Y.

DOOR.

Application filed March 16, 1918.

To all whom it may concern:

Be it known that I, JOHN JOHNSON, a citizen of the United States, and residing at New York, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Doors, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to doors and particularly constructions of this class designed for use in connection with booths, cabinets, closets and the like and to what are known as telephone booths, and the object of the invention is to provide an improved construction of this character with improved means for operating the same, and a further object of the invention 1s to provide a simple, eflicient and practical door construc tion of the class and for the purpose specifled.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a front view of a telephone booth showing my improved door connected therewith and in a closed position;

Fig. 2 a section on the line 22 of Fig. 1 and on an enlarged scale showing my improved door closed in full lines and indicating the same open in dotted lines; and,

Fig. 3 a partial section on the line 33 of Fig. 1 and showing means for.holding my improved door in a closed position.

In the drawing 5 is a telephone booth comprising a back wall 6, side wall 7 a bottom 6 and a top 9, all of which parts are connected in the usual or any desired manner. It will be noted on a careful consideration of Figs. 1 and 2 that the front edge of the top and bottom of the booth is formed into a front face 10 having angular and oppositely directed faces 11, which join the front edge portions of the sides 7 of the booth, as clearly indicated in Fig. 2 of the drawing, and the inner faces of the sides 7 of the booth are provided adjacent to the front edges thereof with arc-shaped recesses 12, as clearly shown in Fig. 2.

Pivotally mounted between the top and bottom of the booth as indicated at 13 in Fig. 2 is my improved door construction 14:,

Specification of Letters Patent.

Serial No. 222,791.

comprising three approximately similar door members 15, 16, and 17. The door member 15 is pivoted to the booth, as shown at 13, while the door member 16 is pivoted to the door member 15 as shown at 18 and the door member 17 is pivoted to the door member 16 as shown at 19, and the outer edge portions of the door members 15 and 17 are rounded as shown at 20 and are adapted to operate in the recesses 12 to seal or provide a tight connection of said door members with the sides 7 of the booth.

The door members 15, 16 and .17 are paneled below the center thereof, as indi cated at 21 in Fig. 1, and provided with glass panels 22 above the center thereof, and the door members 15 and 16 are jointed as shown at 23 in Fig. 2, while the door members 16 and 17 are similarly jointed as shown at 24 in said figure, and the joints 23 and 24 combined with the rounded edges 20 on the door members 15 and 17 serve to close the booth 5, or prevent sound from freely passing into or out from said booth.

It will be noted that the door, or the separate members thereof, when in the closed position conform to the front portion of the top and bottom of the booth, or the central door members 15 and 17 incline backwardly at the opposite sides, and this angular arrangement of the separate members of the door improve the appearance of the booth and also increase the capacity thereof, as will be readily understood, and by the spe- ClfiC arrangement of the separate members of the door, said door is provided with a free or easy action in the operation of openmg and closing the same.

The door 14, or the separate members thereof, are operated by rods 25 and 26, the rod 25 being pivoted to the top 9 of the booth as shown at 27, and to the inner face of the door member 17 as shown at 28 adjacent to the connection of said door member with the member 16, while the rod 26 is pivoted to the top 9 of the booth as shown at 29, and to the inner face of the door member 17 adjacent to the free edge thereof, as shown at 30, and connected with the rods 25 and 26 adjacent to their pivots at 2729 respectively as shown at 31 are coil springs 32 which are also secured to the top 9 of the booth as shown at 33, and these springs serve to hold the separate members of the door it in their open position, or the position indicated in dotted lines in Fig. 2,'but when it is desired to use the booth, the separate members of the door are swung into the full line position shown in Fig. 2 and may be locked in such position by any suitable lock device, but in F ig. 3 of the drawing I have shown at 34 a device of this class of the hook and eye form, it will be understood that when it is desired to vacate the booth by simply releasingthe lock device 34 the separate members of the door will be be thrown open automatically by the springs 32.

The springs 32, as above stated, normally serve to hold the door in its open position, and said door is closed and locked in its closed position against the tension of said springs, and while I have shown the springs 32 connected with the rods 25 and 26, it will be understood that the hinges at 18 and 19 may be spring hinges and a coil spring may be connected with the pivots at 13 to accomplish the same result as said springs 32, 'and changes in an modifications of the details of construction herein shown and described may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire'to secure by Letters Patent, is

1. The combination with a booth having a door opening, of a three-section door having one of its sections hinged to the door amb, the free section folding upon the intermediate one and the latter upon the section which is hinged to the door jamb, rods pivotally connected to the door and to said booth for controlling the door sections and causing one section to fold upon the intermediate section and the intermediate sec tion to fold upon the amb section when the door is opened, and springs for automatically opening the door.

2. The combination with a booth having a door opening, of a folding door mounted in said opening and comprising three sections hinged together, one of said sections In testimony that I claim the foregoing as my invention I have signed my name in presence of the subscribing wltnesses this 14th day of March, 1918.
